Primitive in structure and little changed in over three billion years of fossil record, oxygen producing cyanobacteria is one of the most ancient and widely distributed Earth microorganisms. Today it is regarded as a nuisance and environmental natural hazard. Global warming and intensive human development of the land, coupled with cyanobacteria’s simple environmental demands for light, nutrients, and water, and its proclivity for explosive growth and dominance, give it here-to-fore overlooked potential as a global warming threat to aquatic ecosystems.
Subtropical location, concentrations of chemical fertilizer, agro-business, expanding urban population, and potential threats posed by global warming, put Florida at the forefront for both impacts of global warming and effects of Man-exacerbated cyanobacteria explosion. As a consequence, Florida has experienced cyanobacteria “blooms” of increasing severity and decreasing time interval. Using recent historic trends in human, economic and physical environments, the presentation will use the state to both highlight this threat within the state and example Florida as a harbinger for what is likely to become a common global phenomena.
